- an agricultural system 100 includes a tow bar 102 for attachment to a towing vehicle, such as a tractor.
- the tow bar 102 is in a trailing position relative to a direction of movement V (see FIG. 2A ) along a field 130 and includes a row unit 103 a.
- the row unit 103 a includes a row-cleaning device 104 and a rigid frame 106 for attachment to the tow bar 102
- the row-cleaning device 104 includes a leading coulter 108 and a pair of furrow-opener disks 110 that are attached in a trailing position relative to the leading coulter 108 , each of the furrow-opener disks 110 having a leading edge 110 a adjacent to a trailing edge 108 a of the leading coulter 108 . Only one of the furrow-opener disks 110 is visible in FIG. 1 , with the second of the furrow-opener disks 110 being visible in FIG. 2A .
- the furrow-opener disks 110 have the respective leading edges 110 a adjacent to each other and near the trailing edge 108 a of the leading coulter 108 .
- the leading coulter 108 is positioned such that the leading edges 110 a of the two furrow-opener disks 110 are obscured by the trailing edge 108 a of the leading coulter 108 from a front farming position.
- the front farming position is forward of the row-cleaning device 104 along the direction of movement V along the field 130 .
- the row-cleaning device 104 is attached to the agricultural system 100 in a respective strip position B of a plurality of parallel strip positions along the tow bar 102 .
- the parallel strip positions include at least the strip positions A-D.
- a pivotable row-cleaning linkage 112 is attached to the rigid frame 106 .
- the leading coulter 108 and the furrow-opener disks 110 are coupled to the rigid frame 106 via the pivotable row-cleaning linkage 112 .
- a supplemental force for up-down movement is provided via a row-cleaning actuator 113 .
- the row-cleaning linkage 112 is a parallel linkage according to one exemplary embodiment.
- a first roller device 114 a has a first end 116 a and a second end 118 a .
- the first end 116 a is attached to the rigid frame 106 via a pivotable roller linkage 120 . More specifically, the first end 116 a is directly attached to a separator frame 121 , which, in turn, is attached to the roller linkage 120 .
- the second end 118 a is attached in a similar manner as the first end 116 a , near the parallel strip position A, illustrated in FIG. 2A , and to an adjacent rigid frame via another pivotable roller linkage.
- the roller linkage 120 is independently movable relative to the row-cleaning linkage 112 and, according to an exemplary embodiment, is a parallel linkage.
- a second roller device 114 b has a first end 116 b and a second end 118 b .
- the second roller device 114 b is attached similarly to the first roller device 114 a , with the first end 116 b being attached to an opposite side of the separator frame 121 , for indirect attachment to the rigid frame 106 via the roller linkage 120 .
- the second end 118 b of the second roller device 114 b is near a respective parallel strip position C, illustrated in FIG. 4 , and attached to an adjacent rigid frame via another pivotable roller linkage.
- Each of the roller devices 114 a , 114 b includes a plurality of roller protrusions 128 that extend outwardly from a peripheral surface of the respective roller device 114 a , 114 b .
- the roller protrusions 128 are attached, for example, to the respective peripheral surface via welding or mechanical fasteners.
- One advantage of the roller protrusions 128 is directed to reducing the amount of force required to crush residual plant matter, based on the reduction of surface area of contact surfaces between the roller devices 114 a , 114 b and residual plant matter.
- roller protrusions 128 are integrally formed from a single piece of material, for example, by machining the roller devices 114 a , 114 b with the roller protrusions 128 in a unitary construction.
- the roller devices 114 a , 114 b lack any roller protrusions 128 and are generally cylindrically shaped segments with substantially smooth surfaces.
- the roller devices 114 a , 114 b are generally cylindrically shaped with a hollow (or partially hollow) interior 129 through which a supporting axle is mounted (as illustrated in FIGS. 6 and 7 ) for supporting the rotational motion of the roller devices 114 a , 114 b .
- the roller devices 114 a , 114 b are solid cylinders, with a central hole for accommodating the supporting axle, or partially hollow cylinders.
- Added material in the hollow interior 129 increase the weight and strength of the roller devices 114 a , 114 b to further increase the crushing capability of the roller devices 114 a , 114 b .
- Less material in the hollow interior 129 increase the flexibility of the roller devices 114 a , 114 b to move past terrain obstacles when encountered in the field 130 .
- roller devices 114 a , 114 b are mounted in a trailing position relative to the row-cleaning device 104 .
- the roller devices 114 a , 114 b are mounted in a forward position relative to the row-cleaning device 104 .
- At least one of the roller devices 114 a , 114 b is a crimping device attached to an agricultural device having one or more separators.
- the crimping device is described in more detail in U.S. Patent Application Publication No. 2013/0000535 to Charles H. Martin and Dominic R. Martin, titled “Agricultural Field Preparation Device,” published on Jan. 3, 2013, and which is herein incorporated by reference in its entirety.
- the agricultural system 100 is movable in a direction V along a field 130 in which standing residual plant matter 132 forward of the row-cleaning device 104 is leveled by the roller device 114 a into crushed residual plant matter 134 .
- the residual plant matter such as small grain cover crop, can include (for example) barley, wheat, oats, spelt, rye, clover, weeds, etc.
- the cover crops are typically planted after a primary crop has been harvested, such as corn, in order to reduce compaction of the soil.
- the type of field preparation that typically occurs simultaneously with crushing of the standing residual plant matter 132 is typically planting of a primary crop, such as corn.
- the agricultural system 100 is not limited to planting, and may include spreading fertilizer or other type of field preparation associated with “no-till” or other types of reduced tillage techniques, such as strip-tilling, if desired.
- the agricultural system 100 is configured to include a mini-roller device 115 , instead of the row-cleaning device 104 .
- the mini-roller device 115 is sufficiently large to cover the surface area that would otherwise be strip B.
- the mini-roller device 115 together with the first and second roller devices 114 a , 114 b , level and crush the standing residual plant matter 132 forward of the mini-roller device 115 without creating a strip between the first and second roller devices 114 a , 114 b .
- a single patch of crushed residual plant matter 134 is formed behind the agricultural system 100 .
- the mini-roller device 115 can be a miniature version of the roller device 114 a , being attached to the row-cleaning linkage 112 (instead of the leading coulter 108 and the furrow-opener disks 110 ).
- the mini-roller device 115 can be any size that sufficiently covers the surface area otherwise left uncovered between the first and second roller devices 114 a , 114 b.
- the roller linkage 120 includes a pair of parallel links 123 pivotably coupled between the rigid frame 106 and the separator frame 123 . Pivotable movement of the parallel links 121 allows up-down movement of the roller device 114 a relative to the ground. More specifically, in this example the up-down movement is achieved in response to an actuator force provided by a roller actuator 125 .
- the roller actuator 125 has a movable piston end 127 mounted to the separator frame 123 and a fixed end 129 mounted to the rigid frame 106 .
- the roller actuator 125 is a hydraulic actuator or a pneumatic actuator. The force and movement of the roller actuator 125 and the roller linkage 120 , relative to the rigid frame 106 , is achieved independently of the row-cleaning linkage 112 .
- a roller actuator 125 is coupled at each end of a respective roller device, such as the first end 116 b and the second end 118 b of the second roller device 114 b illustrated in FIG. 4 .
- each row unit such as row units 103 a , 103 b illustrated in FIG. 4 , has at least one respective roller actuator 125 .
- the agricultural system 100 is illustrated having two adjacent row units 103 a , 103 b , mounted along the tow bar 102 at respective parallel strip positions B and C. Although not illustrated, similar or identical row units can be mounted along the tow bar 102 at strip positions A and D.
- Each of the row units 103 a , 103 b includes a respective rigid frame 106 and roller linkage 120 .
- Three roller devices, including the first roller device 114 a , the second roller device 114 b , and a third roller device are 103 c extend from and between respective ones of the row units 103 a , 103 b.
- the second roller device 114 b extends between a first row unit 103 a and a second row unit 103 b .
- the first roller device 114 a extends between the first row unit 103 a and an adjacent row unit that is mounted (but not shown) along the tow bar 102 at the strip position A.
- the third roller device 103 c extends between the second row unit 103 b and an adjacent row unit that is mounted (but not shown) along the tow bar 102 at the strip position D.
- the row units at strip positions A and D are similar and/or identical to the first and second row units 103 a , 103 b.
- the row-cleaning device 104 prepares exposed soil in the strip position B for an agricultural operation, such as planting.
- the roller device 114 a crushes, at least in part, the stems of the standing residual plant matter 132 while maintaining the strip A of exposed soil.
- the roller device 114 a is positioned in a forward position relative to the row-cleaning device 104 , instead of being in the illustrated positioned rearward relative to the row-cleaning device 104 .
- the row-cleaning device 104 moves up-down independent of the roller device 114 a because each is independently attached to and actuated from the rigid frame 106 .
- the roller device 114 a moves pivotably and is actuated in response to a supplemental force provided by the roller actuator 125 , as described above in reference to FIG. 3 .
- the row-cleaning linkage 112 is similarly pivotably attached to the rigid frame 106 and is actuated in response to a supplemental force provided by the row-cleaning actuator 113 .
- the row-cleaning device 104 and the roller device 114 a can be independently adjusted to be positioned at a desired distance from the field irregularity and to apply a desired force to the field irregularity (e.g., a lower force if a rock is encountered, a greater force if hardened soil is encountered, etc.).
- a desired force e.g., a lower force if a rock is encountered, a greater force if hardened soil is encountered, etc.
- the row-cleaning actuator 113 is coupled between the row-cleaning linkage 112 and the rigid frame 106 to provide the desired supplemental force to the respective.
- the row-cleaning actuator 113 is a hydraulic or pneumatic actuator.
- One benefit of the agricultural system 100 in which the row-cleaning device 104 is combined with the roller device 114 a is directed to preparing in a single pas strips of soil despite the presence of standing residual plant matter 132 in the field 130 .
- Such agricultural actions like separating residual plant matter 132 , crushing stems of the residual plant matter 132 , and planting seeds in an open furrow of the strips, all occur within the same pass of the agricultural system 100 .
- the crushed residual plant matter 132 is effectively terminated or destroyed and remains in contact or in close proximity with the surface of the soil, returning nutrients to the soil, such as nitrogen, and thereby reducing the amount of fertilizer that must be subsequently applied to grow the primary crop.
- the crushed residual plant matter 132 remains in contact with or in close proximity with the surface of the soil helps maintain moisture in the soil. It has been shown that such increased moisture retention directly results in an increased yield of the primary crop.
- a toxin is released as a result of which weed growth is substantially diminished without (or reduced) application of herbicides.
- the presence of residual plant matter 132 or cover crop by virtue of the root mass of the residual plant matter 132 , significantly reduces soil erosion that would otherwise occur without such ground cover after harvest of the primary crop.
- the agricultural system 100 is configured with single, centrally located roller bearings 140 for roller devices 114 a - 114 d .
- the roller bearings 140 are centrally located along a central axle 142 within the hollow interior 129 of each roller device 114 a - 14 d .
- the central axle 142 represents a rotational axis along which the roller devices 114 a , 114 d rotate, respectively.
- the roller bearings 140 are mounted to respective supporting brackets 143 .
- the row units 103 a - 103 c independently move up-and-down when obstacles, such as a rock 144 , are encountered.
- the first row unit 103 a moves up to advance past the rock 144 when the second roller device 114 b encounters the rock 144 .
- the rock 144 causes the second roller device 114 b to flex upwards.
- the second roller device 114 b pivots about the central roller bearing 140 and relative to the central axle 142 , with the first end 116 b moving upwards and the second end 118 b moving downwards.
- the movement of the second roller device 114 b causes movement of the first row unit 103 a , which, in turn, causes movement of the first roller device 114 a .
- the first roller device 114 a pivots about its central roller bearing and relative to its central axle 142 , with the first end 116 a moving upwards and the second end 118 a moving downwards.
- the second and third row units 103 b , 103 c , and the third and fourth roller devices 114 c , 114 d remain generally unaffected by the movement of the first row unit 103 a and the first and second roller devices 114 a , 114 b.
- roller bearing 140 instead of a single roller bearing 140 , two roller bearings are centrally located along one or more of the roller devices 114 a - 114 d . Each of the two roller bearings is mounted on a respective, opposite side of the supporting bracket 143 .
- the agricultural system 100 illustrated in FIG. 6 is alternatively configured with two roller bearings 140 at respective ends of the roller devices 114 a - 114 d .
- two side roller bearings 140 are provided for each of the roller devices 114 a - 114 d .
- Each of the side roller bearing 140 is mounted along the central axle 142 to a supporting bracket 143 .
- two side roller bearings 140 are mounted at each end of one or more of the roller devices 114 a - 114 d.
- an agricultural system 200 includes a row unit 201 with a leading residue-clearing sub-assembly 202 followed by a trailing tillage and depth-control sub-assembly 204 . Both sub-assemblies 202 , 204 are carried by a common frame 206 attached to a rear end of a four-bar linkage assembly 208 , which, in turn, is attached to a front frame 210 .
- the front frame 210 is adapted to be connected to the tow bar 102 of a towing vehicle.
- the agricultural system 200 is movable in a direction V along the field 130 .
- both sub-assemblies 202 , 204 are carried by the same frame 206 , the relative relationship of all the components of the two sub-assemblies 202 , 204 remains fixed so that they maintain a consistent set of dynamic properties governed by their relative sizes and positions rather than just the individual properties of the individual components.
- the residue-clearing sub-assembly 202 includes a forward coulter wheel 220 flanked by a pair of toothed wheels 222 , 223 overlapping a rear edge portion of the forward coulter wheel 220 .
- the residue-clearing sub-assembly 202 is similar, but necessarily identical, to the row-cleaning device 104 .
- the forward coulter wheel 220 cuts through the residue on the soil, such as stalks from a previous year's planting, and cuts a shallow slit in the soil.
- the trailing toothed residue-clearing wheels 222 , 223 then kick the cut residue off to opposite sides of the slit cut by the forward coulter wheel 220 , thus clearing a row for planting (e.g., strip rows A-C illustrated in FIG. 1 ), while at the same time cleaning the forward coulter wheel 220 .
- the front edges of the toothed wheels 222 , 223 are tilted inwardly toward the vertical plane of the forward coulter wheel 220 to assist in cleaning the forward coulter wheel 220 , and the lower edges are tilted outwardly to assist in cleaning the row to be planted.
- This arrangement is particularly well suited for strip tilling, where the strip cleared for planting is typically only about 10 inches of the 30-inch center-to-center spacing between planted rows.
- the tillage and depth-control sub-assembly 204 includes a pair of rearward coulter wheels 230 , 231 that are offset from each other both laterally and fore and aft, and two gauge wheels 232 , 233 .
- the rear edges of the rearward coulter wheels 230 , 231 are tilted inwardly toward the slit cut by the forward coulter wheel 220 , and the lower edges of the rearward coulter wheels 230 , 213 are tilted outwardly away from the slit.
- each of the rearward coulter wheels 230 , 231 makes contact with the soil at an angle in two planes, causing each of the rearward coulter wheels 230 , 231 to apply a force to the soil that is upward and toward the center of the row.
- the aggregate effect of this angular relationship on the soil is a turbulent swirling and mixing of the soil in the space between the two rearward coulter wheels 230 , 231 .
- the turbulent swirling and mixing of the soil incorporates air and residue into the soil, and, further, breaks the soil into finer pieces. Soil thrown laterally by the leading coulter wheel 230 is caught by the trailing coulter wheel 231 to retain that soil in the tilled area between the two rearward coulter wheels 230 , 231 and to form a ridge for planting.
- the gauge wheels 232 , 233 control the depth to which the row unit 201 penetrates into the soil, and also intercept soil and residue thrown upwardly and laterally by the trailing coulter wheel 231 , to retain that soil in the strip being tilled. This prevents soil loss form the tilled area and facilitates the creation of the ridge, or berm, which is desirable for planting. Because the height of the axes of rotation of all the wheels 220 , 222 , 223 , 230 , 231 is fixed relative to the height of the axes of rotation of the gauge wheels 232 , 233 , the interaction among all the wheels remains essentially the same at all times.
- the row unit 201 includes small-belted caterpillar tracks or similar devices for controlling the depth.
- Each of the gauge wheels 232 , 233 includes a swirl device 240 having multiple tines 242 and being attached to a central portion of the inboard side of each respective gauge wheel 232 , 233 .
- the swirl device 240 is located rearwardly of the of the tillage device (e.g., rearward coulter wheels 230 , 231 ) and is positioned to intercept soil and residue displaced upwardly by the tillage device.
- the swirl device 240 rotates with the respective gauge wheel 232 , 233 and helps to control the distribution of soil moving toward the respective gauge wheel 232 , 233 from the rearmost of the coulter wheels 220 , 230 , 231 .
- the swirl device 240 intercepts a portion of the soil and residue thrown upwardly and laterally towards the gauge wheels 232 , 233 by the trailing coulter wheel 231 and distributes the intercepted soil and residue across the tilled strip adjacent the gauge wheels 232 , 233 .
- the swirl device 240 also helps to break up clumpy soil. Because the outside diameter of the swirl device 240 is smaller than the outside diameter of the gauge wheels 232 , 233 , the swirl device 240 operates above ground level and does not dig into the earth.

Abstract
Description
- The present invention relates generally to agricultural equipment and, more particularly, to a system having a roller device for preparing a field with leftover residual plant matter.
- As plant matter is leftover on a field from one season to the next, farming operations continue to struggle with residual stubble when preparing the field for a new crop. These challenges are especially evident in no-till farming, which has become more popular over the recent years. For example, planting seeds between rows of leftover corn stalks is difficult without removing or minimizing the presence of the corn stalks in the planted rows.
- Thus, it would be desirable to develop a system that overcomes the problems and limitations associated with leftover residual plant matter.
- In accordance with one embodiment, an agricultural system includes a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field. The system further includes a plurality of row-cleaning devices attached in parallel strip positions along the tow bar, and at least one roller device. Each row-cleaning device includes a rigid frame for attachment to the tow bar, a leading coulter, and one or more furrow-opener disks. The furrow-opener disks are in a trailing position relative to the leading coulter, each of the furrow-opener disks having a leading edge adjacent to a trailing edge of the leading coulter. Each row-cleaning device further includes a pivotable row-cleaning linkage attached to the rigid frame, the leading coulter and the furrow-opener disks being coupled to the rigid frame via the pivotable row-cleaning linkage. The roller device extends between two adjacent parallel strip positions and is attached at each end to a respective rigid frame via a respective pivotable roller linkage. The pivotable roller linkage is independently movable relative to the pivotable row-cleaning linkage.
- In accordance with another embodiment, an agricultural system includes a tow bar for attachment to a towing vehicle in a trailing position relative to a direction of movement along a field. The system further includes a plurality of row-cleaning devices attached in parallel strip positions along the tow bar, the plurality of row-cleaning devices including a first row-cleaning device and a second row-cleaning device. The first row-cleaning device is attached in a first strip position and includes a first rigid frame for attachment to the tow bar, a first leading coulter, and one or more first furrow-opener disks in a trailing position relative to the first leading coulter. The first row-cleaning device includes a first pivotable row-cleaning linkage attached to the first rigid frame, the first leading coulter and the first furrow-opener disks being coupled to the first rigid frame via the first pivotable row-cleaning linkage. The second row-cleaning device is attached in a second strip position, the second strip position being adjacent and parallel to the first strip position, the second row-cleaning device including a second rigid frame for attachment to the tow bar, a second leading coulter, one or more second furrow-opener disks in a trailing position relative to the second leading coulter. The second row-cleaning device further includes a second pivotable row-cleaning linkage attached to the second rigid frame, the second leading coulter and the second furrow-opener disks being coupled to the second rigid frame via the second pivotable row-cleaning linkage. The system further includes a roller device attached between the first row-cleaning device and the second row-cleaning device, the roller device including a first pivotable roller linkage attached at a first end of the roller device and being independently movable from the first rigid frame. The roller device further includes a second pivotable roller linkage attached at a second end of the roller device and being independently movable from the second rigid frame, and at least one roller bearing mounted along a rotational axis of the roller device.

- Turning now to the drawings and referring first to
FIGS. 1 and 2A , anagricultural system 100 includes atow bar 102 for attachment to a towing vehicle, such as a tractor. Thetow bar 102 is in a trailing position relative to a direction of movement V (seeFIG. 2A ) along afield 130 and includes arow unit 103 a. - The
row unit 103 a includes a row-cleaning device 104 and arigid frame 106 for attachment to thetow bar 102 The row-cleaning device 104 includes a leadingcoulter 108 and a pair of furrow-opener disks 110 that are attached in a trailing position relative to the leadingcoulter 108, each of the furrow-opener disks 110 having a leadingedge 110 a adjacent to atrailing edge 108 a of the leadingcoulter 108. Only one of the furrow-opener disks 110 is visible inFIG. 1 , with the second of the furrow-opener disks 110 being visible inFIG. 2A . - More specifically, the furrow-
opener disks 110 have the respective leadingedges 110 a adjacent to each other and near thetrailing edge 108 a of the leadingcoulter 108. The leadingcoulter 108 is positioned such that the leadingedges 110 a of the two furrow-opener disks 110 are obscured by thetrailing edge 108 a of the leadingcoulter 108 from a front farming position. The front farming position is forward of the row-cleaning device 104 along the direction of movement V along thefield 130. - The row-
cleaning device 104 is attached to theagricultural system 100 in a respective strip position B of a plurality of parallel strip positions along thetow bar 102. As further illustrated inFIG. 4 , and described in more detail below, the parallel strip positions include at least the strip positions A-D. - A pivotable row-
cleaning linkage 112 is attached to therigid frame 106. The leadingcoulter 108 and the furrow-opener disks 110 are coupled to therigid frame 106 via the pivotable row-cleaning linkage 112. Additionally, a supplemental force for up-down movement is provided via a row-cleaning actuator 113. The row-cleaning linkage 112 is a parallel linkage according to one exemplary embodiment. - A
first roller device 114 a has afirst end 116 a and asecond end 118 a. Thefirst end 116 a is attached to therigid frame 106 via apivotable roller linkage 120. More specifically, thefirst end 116 a is directly attached to aseparator frame 121, which, in turn, is attached to theroller linkage 120. Thesecond end 118 a is attached in a similar manner as thefirst end 116 a, near the parallel strip position A, illustrated inFIG. 2A , and to an adjacent rigid frame via another pivotable roller linkage. Theroller linkage 120 is independently movable relative to the row-cleaning linkage 112 and, according to an exemplary embodiment, is a parallel linkage. - A
second roller device 114 b has afirst end 116 b and asecond end 118 b. Thesecond roller device 114 b is attached similarly to thefirst roller device 114 a, with thefirst end 116 b being attached to an opposite side of theseparator frame 121, for indirect attachment to therigid frame 106 via theroller linkage 120. Thesecond end 118 b of thesecond roller device 114 b is near a respective parallel strip position C, illustrated inFIG. 4 , and attached to an adjacent rigid frame via another pivotable roller linkage. - Each of the
roller devices roller protrusions 128 that extend outwardly from a peripheral surface of therespective roller device roller protrusions 128 is directed to reducing the amount of force required to crush residual plant matter, based on the reduction of surface area of contact surfaces between theroller devices roller protrusions 128 are integrally formed from a single piece of material, for example, by machining theroller devices roller protrusions 128 in a unitary construction. Alternatively yet, theroller devices roller protrusions 128 and are generally cylindrically shaped segments with substantially smooth surfaces. - The
roller devices FIGS. 6 and 7 ) for supporting the rotational motion of theroller devices roller devices hollow interior 129 increase the weight and strength of theroller devices roller devices hollow interior 129 increase the flexibility of theroller devices field 130. - In the illustrated embodiment, the
roller devices device 104. However, in an alternative embodiment theroller devices device 104. - In yet other alternative embodiments, at least one of the
roller devices - The
agricultural system 100 is movable in a direction V along afield 130 in which standingresidual plant matter 132 forward of the row-cleaningdevice 104 is leveled by theroller device 114 a into crushedresidual plant matter 134. The residual plant matter, such as small grain cover crop, can include (for example) barley, wheat, oats, spelt, rye, clover, weeds, etc. - The cover crops are typically planted after a primary crop has been harvested, such as corn, in order to reduce compaction of the soil. The type of field preparation that typically occurs simultaneously with crushing of the standing
residual plant matter 132 is typically planting of a primary crop, such as corn. However, theagricultural system 100 is not limited to planting, and may include spreading fertilizer or other type of field preparation associated with “no-till” or other types of reduced tillage techniques, such as strip-tilling, if desired. - Referring to
FIG. 2B , theagricultural system 100 is configured to include amini-roller device 115, instead of the row-cleaningdevice 104. Themini-roller device 115 is sufficiently large to cover the surface area that would otherwise be strip B. As such, themini-roller device 115, together with the first andsecond roller devices residual plant matter 132 forward of themini-roller device 115 without creating a strip between the first andsecond roller devices residual plant matter 134 is formed behind theagricultural system 100. - The
mini-roller device 115 can be a miniature version of theroller device 114 a, being attached to the row-cleaning linkage 112 (instead of the leadingcoulter 108 and the furrow-opener disks 110). Optionally, themini-roller device 115 can be any size that sufficiently covers the surface area otherwise left uncovered between the first andsecond roller devices - Referring to
FIG. 3 , theroller linkage 120 includes a pair ofparallel links 123 pivotably coupled between therigid frame 106 and theseparator frame 123. Pivotable movement of theparallel links 121 allows up-down movement of theroller device 114 a relative to the ground. More specifically, in this example the up-down movement is achieved in response to an actuator force provided by aroller actuator 125. - The
roller actuator 125 has amovable piston end 127 mounted to theseparator frame 123 and afixed end 129 mounted to therigid frame 106. According to some examples, theroller actuator 125 is a hydraulic actuator or a pneumatic actuator. The force and movement of theroller actuator 125 and theroller linkage 120, relative to therigid frame 106, is achieved independently of the row-cleaning linkage 112. - A
roller actuator 125 is coupled at each end of a respective roller device, such as thefirst end 116 b and thesecond end 118 b of thesecond roller device 114 b illustrated inFIG. 4 . Thus, each row unit, such asrow units FIG. 4 , has at least onerespective roller actuator 125. - Referring to
FIG. 4 , theagricultural system 100 is illustrated having twoadjacent row units tow bar 102 at respective parallel strip positions B and C. Although not illustrated, similar or identical row units can be mounted along thetow bar 102 at strip positions A and D. Each of therow units rigid frame 106 androller linkage 120. Three roller devices, including thefirst roller device 114 a, thesecond roller device 114 b, and a third roller device are 103 c extend from and between respective ones of therow units - For example, the
second roller device 114 b extends between afirst row unit 103 a and asecond row unit 103 b. Thefirst roller device 114 a extends between thefirst row unit 103 a and an adjacent row unit that is mounted (but not shown) along thetow bar 102 at the strip position A. Thethird roller device 103 c extends between thesecond row unit 103 b and an adjacent row unit that is mounted (but not shown) along thetow bar 102 at the strip position D. The row units at strip positions A and D are similar and/or identical to the first andsecond row units - Referring to
FIG. 5 , the row-cleaningdevice 104, including the leadingcoulter 108 and the furrow-opener disk 110, prepares exposed soil in the strip position B for an agricultural operation, such as planting. Theroller device 114 a crushes, at least in part, the stems of the standingresidual plant matter 132 while maintaining the strip A of exposed soil. Alternatively, theroller device 114 a is positioned in a forward position relative to the row-cleaningdevice 104, instead of being in the illustrated positioned rearward relative to the row-cleaningdevice 104. - Furthermore, as the
agricultural system 100 advance in the direction V along thefield 130, the row-cleaningdevice 104 moves up-down independent of theroller device 114 a because each is independently attached to and actuated from therigid frame 106. Theroller device 114 a moves pivotably and is actuated in response to a supplemental force provided by theroller actuator 125, as described above in reference toFIG. 3 . In reference to the row-cleaningdevice 104, the row-cleaning linkage 112 is similarly pivotably attached to therigid frame 106 and is actuated in response to a supplemental force provided by the row-cleaningactuator 113. Thus, as the row-cleaningdevice 104 and theroller device 114 a encounter different field irregularities or obstacles, such as rocks, irregular terrain surfaces, and/or other debris, the row-cleaningdevice 104 and theroller device 114 a can be independently adjusted to be positioned at a desired distance from the field irregularity and to apply a desired force to the field irregularity (e.g., a lower force if a rock is encountered, a greater force if hardened soil is encountered, etc.). - The row-cleaning
actuator 113 is coupled between the row-cleaning linkage 112 and therigid frame 106 to provide the desired supplemental force to the respective. The row-cleaningactuator 113, by way of example, is a hydraulic or pneumatic actuator. - One benefit of the
agricultural system 100, in which the row-cleaningdevice 104 is combined with theroller device 114 a is directed to preparing in a single pas strips of soil despite the presence of standingresidual plant matter 132 in thefield 130. Such agricultural actions like separatingresidual plant matter 132, crushing stems of theresidual plant matter 132, and planting seeds in an open furrow of the strips, all occur within the same pass of theagricultural system 100. - Additional benefits of the
agricultural system 100 are directed to the crushedresidual plant matter 132. For example, the crushedresidual plant matter 134 is effectively terminated or destroyed and remains in contact or in close proximity with the surface of the soil, returning nutrients to the soil, such as nitrogen, and thereby reducing the amount of fertilizer that must be subsequently applied to grow the primary crop. In another example, the crushedresidual plant matter 132 remains in contact with or in close proximity with the surface of the soil helps maintain moisture in the soil. It has been shown that such increased moisture retention directly results in an increased yield of the primary crop. In yet another example, by virtue of the crushedresidual plant matter 132 remaining in contact or in close proximity with the surface of the soil, a toxin is released as a result of which weed growth is substantially diminished without (or reduced) application of herbicides. In yet another example, the presence ofresidual plant matter 132 or cover crop, by virtue of the root mass of theresidual plant matter 132, significantly reduces soil erosion that would otherwise occur without such ground cover after harvest of the primary crop. - Referring to
FIG. 6 , theagricultural system 100 is configured with single, centrally locatedroller bearings 140 for roller devices 114 a-114 d. Theroller bearings 140 are centrally located along acentral axle 142 within thehollow interior 129 of each roller device 114 a-14 d. Thecentral axle 142 represents a rotational axis along which theroller devices roller bearings 140 are mounted to respective supportingbrackets 143. As theagricultural system 100 is advanced along thefield 130, therow units 103 a-103 c independently move up-and-down when obstacles, such as arock 144, are encountered. - For example, the
first row unit 103 a moves up to advance past therock 144 when thesecond roller device 114 b encounters therock 144. Therock 144 causes thesecond roller device 114 b to flex upwards. Thesecond roller device 114 b pivots about thecentral roller bearing 140 and relative to thecentral axle 142, with thefirst end 116 b moving upwards and thesecond end 118 b moving downwards. The movement of thesecond roller device 114 b causes movement of thefirst row unit 103 a, which, in turn, causes movement of thefirst roller device 114 a. Thefirst roller device 114 a, similar to thesecond roller device 114 b, pivots about its central roller bearing and relative to itscentral axle 142, with thefirst end 116 a moving upwards and thesecond end 118 a moving downwards. The second andthird row units fourth roller devices first row unit 103 a and the first andsecond roller devices - Optionally, instead of a
single roller bearing 140, two roller bearings are centrally located along one or more of the roller devices 114 a-114 d. Each of the two roller bearings is mounted on a respective, opposite side of the supportingbracket 143. - Referring to
FIG. 7 , theagricultural system 100 illustrated inFIG. 6 is alternatively configured with tworoller bearings 140 at respective ends of the roller devices 114 a-114 d. Thus, instead of a single, centrally located,roller bearing 140, twoside roller bearings 140 are provided for each of the roller devices 114 a-114 d. Each of theside roller bearing 140 is mounted along thecentral axle 142 to a supportingbracket 143. Optionally, for increased flexibility in pivoting movement, twoside roller bearings 140 are mounted at each end of one or more of the roller devices 114 a-114 d. - Referring to
FIG. 8 , anagricultural system 200 includes a row unit 201 with a leading residue-clearing sub-assembly 202 followed by a trailing tillage and depth-control sub-assembly 204. Bothsub-assemblies common frame 206 attached to a rear end of a four-bar linkage assembly 208, which, in turn, is attached to afront frame 210. Thefront frame 210 is adapted to be connected to thetow bar 102 of a towing vehicle. Theagricultural system 200 is movable in a direction V along thefield 130. Because bothsub-assemblies same frame 206, the relative relationship of all the components of the twosub-assemblies - The residue-
clearing sub-assembly 202 includes a forward coulter wheel 220 flanked by a pair oftoothed wheels forward coulter wheel 220. Thus, the residue-clearing sub-assembly 202 is similar, but necessarily identical, to the row-cleaningdevice 104. The forward coulter wheel 220 cuts through the residue on the soil, such as stalks from a previous year's planting, and cuts a shallow slit in the soil. The trailing toothed residue-clearingwheels forward coulter wheel 220, thus clearing a row for planting (e.g., strip rows A-C illustrated inFIG. 1 ), while at the same time cleaning theforward coulter wheel 220. To this end, the front edges of thetoothed wheels forward coulter wheel 220, and the lower edges are tilted outwardly to assist in cleaning the row to be planted. This arrangement is particularly well suited for strip tilling, where the strip cleared for planting is typically only about 10 inches of the 30-inch center-to-center spacing between planted rows. - The tillage and depth-
control sub-assembly 204 includes a pair ofrearward coulter wheels gauge wheels rearward coulter wheels forward coulter wheel 220, and the lower edges of therearward coulter wheels 230, 213 are tilted outwardly away from the slit. Thus, each of therearward coulter wheels rearward coulter wheels rearward coulter wheels coulter wheel 230 is caught by the trailingcoulter wheel 231 to retain that soil in the tilled area between the tworearward coulter wheels - The
gauge wheels coulter wheel 231, to retain that soil in the strip being tilled. This prevents soil loss form the tilled area and facilitates the creation of the ridge, or berm, which is desirable for planting. Because the height of the axes of rotation of all thewheels gauge wheels - Each of the
gauge wheels swirl device 240 havingmultiple tines 242 and being attached to a central portion of the inboard side of eachrespective gauge wheel swirl device 240 is located rearwardly of the of the tillage device (e.g.,rearward coulter wheels 230, 231) and is positioned to intercept soil and residue displaced upwardly by the tillage device. Theswirl device 240 rotates with therespective gauge wheel respective gauge wheel coulter wheels - The
swirl device 240 intercepts a portion of the soil and residue thrown upwardly and laterally towards thegauge wheels coulter wheel 231 and distributes the intercepted soil and residue across the tilled strip adjacent thegauge wheels swirl device 240 also helps to break up clumpy soil. Because the outside diameter of theswirl device 240 is smaller than the outside diameter of thegauge wheels swirl device 240 operates above ground level and does not dig into the earth. Another benefit of theswirl device 240 is that it produces thorough incorporation of fertilizer, especially dry fertilizer, with the soil within the worked strip where it is needed by the plants, rather than leaving the fertilizer in concentrated ribbons. This allows the application of more fertilizer in the strip, possibly just ahead of the planter by a few hours, without burning the seed, and may eliminate a second trip to side dress. The total amount of fertilizer applied to produce optimum crop yields may even be reduced. Fertilizer that is not thoroughly incorporated in the soil may be lost to the atmosphere or runoff, which is costly and may pollute both ground water and surface water. - In the embodiment described above, all the
coulter wheels wheels - The illustrative row unit 201 is urged downwardly against the soil by its own weight. If it is desired to have the ability to increase this downward force, or to be able to adjust the force, a hydraulic or pneumatic cylinder and/or one or more springs may be added between the
common frame 206 and the four-bar linkage assembly 208, or between thecommon frame 206 and thefront frame 210, to urge thecommon frame 206 downwardly with a controllable force. Such a hydraulic cylinder may also be used to lift the row unit off the ground for transport by a heavier, stronger, fixed-height frame that is also used to transport large quantities of fertilizer for application via multiple residue-clearing and tillage row units. - The
agricultural system 200 further includes a roller device 250 that is mounted for crushing residual plant matter. The configuration and/or attachment of the roller device 250 is similar to and/or identical to the roller devices 114 a-114 d described above in reference toFIGS. 1-7 . In the illustrated embodiment ofFIG. 8 , the roller device 250 is in a trailing position relative to theforward coulter wheel 220. However, in alternative embodiments the roller device 250 is positioned in other desired positions relative to theforward coulter wheel 220. - Referring to
FIGS. 9 and 10 , theagricultural system 200 includes tworoller devices agricultural system 200 is advanced in direction V along thefield 103, theroller devices residual plant matter 132 into crushedresidual plant matter 134. Simultaneously, the row units 201 a-201 c prepare strips of soil A-C in preparation for planting or other farming operation. - In alternative embodiments one or more of the wheels described above are forged blades with an induction hardened edge. The forged blades are beneficial because they are ductile and, as such, are not prone to shatter. Furthermore, in addition to being resisting to shattering, the forged blades maintain a hardened edge. In a further optional embodiment, one or more of the coulters described above is made of cast iron and includes a beveled edge.
- In other alternative embodiments, various hydraulic configurations are included in one or more of the
agricultural systems agricultural systems - It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrated embodiment and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
